Answer:
We get the value of x: x = 3
Explanation:
Point G lies between points F and H on Line segment F H.
Space between F and G = 4x
Space between G and H = 2x
Length of FH = 18
We need to find value of x.
As point G lies between point F and H, sum of FG and GH will give FH, we can write

Putting values to make equation

Now, solving the equation we can find value of x

So, we get the value of x: x = 3
